Sec. 2 : Fuels & Energy
Differences between Fuel and Energy
What are the forms of energy?
The laws of thermodynamics |
|
1st Law: Energy cannot be destroyed or created, it can only change form.
BUT WHAT DOES THIS MEAN?!?!
Well simply it means that although a matchstick may burn, no real energy is created, only changes form. For example the matchstick uses up chemical energy to change it into light and heat energy.
Energy has two main branches: Potential and Kinetic.
2nd Law: Every time energy changes form, they have less quality and higher entropy.\
But WHAT DOES THIS MEAN??!?!?!
Entropy is the capacity to go from order to disorder, simply put, the energy changes into a less uniform type.

FOssil Fuels
Fossil fuels contain high amounts of Carbon, that which has a lot of bonds and has a lot of bonds; bonds which hold a lot of potential energy.
When a fossil fuel is burnt, potential chemical energy is turnt into heat and light energy.
